Each line positive sequence impedance is shown in the calculations Summary tables.
As well as the relation between the return path resistance and line resistance R E/R L, and the relation between the return path reactance and line reactance X E/X L as depicted in the picture. Magnitude and angle of the coefficient K 0 for each line are calculated automatically, it is used for distance protection coordination. Coefficient K 0 , relations R E/R L, and X E/X L are 0 for transformers.
